blockintql 1.2.9

BlockINTQL — Sovereign Blockchain Intelligence CLI

BlockINTQL

Blockchain intelligence from the command line. Screen addresses against sanctioned entities and known threat actors, trace fund flows, search Bitcoin OP_RETURN messages, and run AI-powered forensic analysis — from your terminal or your AI agent.

pip install blockintql

30-Second Start

blockintql init                              # generates API key, saves it locally
blockintql verdict --address 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa

That's it. You get a CLEAR, CAUTION, or BLOCK verdict backed by OFAC sanctions data, pig butchering heuristics, exchange labels, and community-submitted intelligence.

  CLEAR  ·  0/100 risk  ·  SAFE

  address  1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
  chain    bitcoin
  entity   Satoshi Nakamoto (Genesis Block)

Commands

Intelligence (2 credits)

Command	What it does
verdict	Fast CLEAR / CAUTION / BLOCK decision for any address
screen	Full counterparty screening with sanctions, mixing, darknet flags
ens	Resolve ENS name to address with risk check

Analysis (5–20 credits)

Command	What it does
analyze	AI-powered multi-agent forensic analysis
trace	FIFO/LIFO fund tracing across hops
query	Natural language — ask anything about an address or transaction
profile	Search the OP_RETURN identity graph by email, handle, phone, PGP key

Community (free)

Command	What it does
report	Submit an address label — earn credits when approved
list-categories	Valid label categories (SANCTIONS, PIG_BUTCHERING, RANSOMWARE, etc.)
leaderboard	Top community contributors
set-name	Set your display name on the leaderboard

Setup

Command	What it does
init	Generate an API key instantly — no email required
auth	Save an existing API key (reads env var or interactive prompt)
buy	Purchase credit packs ($10 / 1,000 or $40 / 5,000)
pay	Configure x402 USDC auto-pay on Base
status	API health check
providers	List available attribution providers
capabilities	Full command reference for agents

Agent Mode

Every command supports --agent for structured JSON output and --quiet to suppress progress text. Pipe to jq, feed to your LLM, or embed in CI:

RESULT=$(blockintql verdict --address $ADDR --chain bitcoin --agent --quiet)
SAFE=$(echo $RESULT | jq -r '.safe')
if [ "$SAFE" != "true" ]; then
  echo "Blocked: $(echo $RESULT | jq -r '.risk_indicators')"
  exit 1
fi

MCP Server

For Claude, Cursor, or any MCP-compatible agent:

Agent Skill

Dump the skill prompt into your agent's context:

blockintql capabilities --install >> CONTEXT.md

Provider Enrichment

Combine BlockINTQL's database with your existing Chainalysis, TRM, Elliptic, Crystal, or Merkle Science subscription. The CLI calls your provider directly from your machine — your provider key never touches BlockINTQL servers.

export BLOCKINTQL_PROVIDER_KEY=your_chainalysis_key
blockintql screen --address 0x742d... --chain ethereum --provider chainalysis

Both results merge into a single verdict. BlockINTQL sees the address; your provider sees the address + your key. The two never cross.

Available providers: chainalysis, trm, elliptic, crystal, merkle_science, nomis, generic

Privacy Architecture

This CLI is open source so you can verify every claim.

What stays on your machine:

• Provider API keys — never sent to BlockINTQL, never logged, never proxied
• Config file (~/.blockintql/config.json) — stored with 0600 permissions

What the BlockINTQL API receives per command:

Command	Data sent
verdict	address, chain, context (if supplied)
screen	address, chain
analyze	query text, addresses, chain, output format
profile	identifier, type
trace	txid, hops, method
query	natural-language question
buy	email
ens	ENS name

The narrow claim is: provider keys never leave your machine. We don't make broader claims than the code supports. Read blockintql/cli.py — it's 550 lines, not a thousand-file monorepo.

Response Schema

All screening commands return:

{
  "verdict": "CLEAR | CAUTION | BLOCK",
  "safe": true,
  "risk_score": 0,
  "chain": "bitcoin",
  "entity": "Coinbase",
  "risk_indicators": [],
  "narrative": "..."
}

screen adds: sanctions_hit, mixing_detected, darknet_exposure, exchange_identified

Risk score semantics: 0–30 low, 30–70 medium, 70+ high. >= 70 should block in automated pipelines.

Chain Handling

Defaults to --chain bitcoin. Pass --chain ethereum for 0x addresses.

Commands that auto-detect chain: ens (always Ethereum), query (inferred), analyze (defaults Ethereum).

Auth

# Option 1: env var (recommended — avoids shell history)
export BLOCKINTQL_API_KEY=biq_sk_live_...

# Option 2: interactive prompt
blockintql auth

# Option 3: generate a new key
blockintql init

Auth precedence: API key → x402 auto-pay → free tier (10/day).

Development

git clone https://github.com/block6iq/blockintql-cli.git
cd blockintql-cli
pip install -e .
pytest tests/ -v

The test suite includes privacy invariant tests that assert provider keys never appear in any request to the BlockINTQL API — headers, body, params, or URL. These run on every command that supports provider enrichment.
